Abstract: 1356077 Stabilizing waste material GENERAL SIGNAL CORP 13 Dec 1972 [11 April 1972] 57521/72 Heading C1C Waste material (e.g. raw waste, sewage, primary clarifier effluent or secondary sludge) is stabilized by mixing the material with an oxidizing agent and subjecting the mixture to rapid circulation under pressure in a first zone to provide oxidation of the material, recirculating a major portion of the mixture from a first zone back through this zone and subjecting the remaining portion of the mixture from the first zone to further cirulation under pressure in a second zone to promote further oxidation of the material. The process may be carried out in the apparatus shown in the accompanying Figure wherein waste material entering along conduit 10 is mixed with an oxidizing agent, e.g. chlorine gas supplied from means 14, and passed via pump 12 and tangentially positioned nozzle 18 into tank 20. Mixture discharged from this tank via conduit 22 is partially recirculated to the tank 20, the remainder being fed to a second reaction tank 30 for further treatment. The flow restrictor 28 and the pump 34, which is arranged to operate in opposition to the direction of flow from the second tank, maintain the required high pressures in the first and second tanks respectively. The tangentially positioned nozzle 18 and a similarly positioned nozzle serving tank 30 provide a circulatory flow of waste material within the tanks.

Abstract: 745,147. Moving coil meters. SANGAMO WESTON, Ltd. Feb. 19, 1953 [Feb. 20, 1952], No. 4719/53. Class 37. A plurality of coupled coaxial coils move in the same air gap between a roughly cylindrical core magnetized transverse to its axis and an enclosing yoke which lies generally in the plane of magnetization of the core. The coils are mounted in separate sets of bearings. In the embodiment shown in Fig. 3 one coil C<SP>1</SP> has bearings in the yoke Y while the other C is borne by the core, which is screwed to a plate 1 bolted to the yoke Y. The upper coil staffs carry spiral coupling springs 11, 11<SP>1</SP> insulated from the coils, the outer ends of the springs being attached to a single indicating pointer 9. As shown in Fig. 3A, the staff supports 14, 141 of the coils C, C' are long and threaded and have extended heads cemented to their respective coils. These supports carry insulating washers 15, 16, 151, 16<SP>1</SP> between which are sandwiched the coupling spring abutments 17, 17<SP>1</SP> which are thus insulated from the staffs. Electrical connections to the coils are made via controlling springs S, S<SP>1</SP>, the abutments 28, 28<SP>1</SP> and the nuts 29, 29<SP>1</SP> to the staff supports. In a modification the pointer and springs 11, 11<SP>1</SP> are replaced by a single pointer on the outer coil and the outer ends of the upper control springs for the two coils are connected together by a rigid bar instead of to fixed points. This instrument may be used as a ratiometer by making a common connection to one end of the coils via the bar and making independent connections to the other ends through the lower control springs. In a further embodiment the inner coil is carried on bearings in a subframe which forms an extension of the frame carrying the core, this frame being bolted to the yoke. The instrument has small overall dimensions for a given coil size, a feature of importance in such applications as the instrument panel of an aircraft. The instrument may be lightened by making parts of the yoke not required for the magnetic circuit of light plastics. Specification 720,744 is referred to.
